BALENG- PRESS.

SPECIFICATION forming part of Letters Fatent No. 680,841, dated August 20, 1901.

Application filed April 24, 1901.

To aZZ whom it may concern:

Be it known that I, ROBERT E. CHAPMAN, a

citizen of the United States, residing at Cherokee, in the county of San Saba and State of Texas, have invented a new and useful Baling-Press, of which the following is a specification.

My invention is an improved baling press; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is a vertical longitudinal sectional view showing the operative parts of my improved baling-press. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation of the same, showing the horse-power and the plunger-rod connected to the pitman thereof. Fig. 4 is a horizontal sectional view taken on a plane indicated by the line a a of Fig. 3. Fig. 5 is a detail perspective view illustrating the construction of one of the division-blocks. Fig. 6 is a detail side elevation of the horse-power for operating the plunger of the press. Fig. 7 is a top plan view of the same. Fig. 8 is an end elevation of the same. Fig. 9 is a detail sectional view showing the guiding-head for the plunger-rod. Fig. 10 is a transverse sectional view of the press, showing the feedtable disposed in operative position on one side thereof.

The sills 1 of the main frame comprise the sections 2, 3, and 4., which are detachably secured together, as by bolts 5. On the sections 2 of the sills is erected the press-box 6, which is of suitable length, and the sides 7, top 8, and bottom 9 of which extend longitudinally in one direction to form a bale-chamber 10, which when the press is in operation contains the bales after they are formed and from which the bales are successively ejected by the action of the plunger in the formation of a new bale. Yoke-bars 11 12 are disposed, respectively under the bottom and over the top of the chamber 10, near the outer end thereof, and are connected together by boltrods 13, by means of which the yoke-bar 12 may be depressed to correspondingly depress the outer end of the top 8, and thereby contract the discharge-opening 14 at the outer end of the chamber 10. Similar yoke-bars 15 are disposed on the sides 7 of chamber 10, near Serial No. 57,286. (No model.)

the discharge end of the latter, and are connected together by bolt-rods 16, by means of which they may be adjusted to contract the space between the sides 7 at the discharge end of chamber 10. By this construction the discharge end of the bale-chamber 10 maybe contracted, both vertically and laterally, to retard the passage therethrough of the finished bales, and hence cause the bales to be compressed by the plunger to the desired density.

That portion of the press-box which is at the front end of the chamber 10 I call the baling-chamber 17, in which the bales are formed and from which the bales are moved by the subsequent action of the plunger 18 into the bale-chamber 10. The said balingchamber 17 is provided with vertically-extending sides 19 of suitable height, and a feed-opening 20 is formed on the upper side of said baling-chamber between the vertical sides 19. Condensing-boards 21 are disposed between the vertical sides 19 and are hinged near their lower sides on the frame of the press-box, as at 22, and said condensingboards are adapted to move from the inclined positions shown in Fig. 1 of the drawings to a vertical position, as will be understood. On the outer sides of said condensing-boards,near their upper edges, are yokes 23, which operate in curved slots 24: in the vertical sides 19, said curved slots being concentric with the pivotal axes of the hinges 22. Springs 25, which project outward from the condensingboards and are secured on the frame of the press-box, have their outer ends connected to the yokes 23, as at 26. The function of said springs, as will be understood, is to normally retain the condensing-boards 21 in the inclined positions shown in Fig. l. The said condensing-boards, on their inner sides near their upper edges,are provided With inwardlyprojecting downturned teeth 27 of suitable length.

In the sides of the baling-chamber 17 at the front end of the balechamber 10 are disposed pivoted dogs 28, which are pressed inward by the springs 29. The said dogs by engagement with a bale as the same is forced rearward from the baling-chamber 17 into the bale-chamber 10 prevent reverse movement of the halo when the same is released by the outstroke of the plunger. From the front side of the plunger 18 extends the plungerrod 30, which is of suitable length and is maintained against lateral movement and directed in a straight line by a guide-head 31, in which are rollers 32, that bear on opposite sides of said plunger-rod. The latter is provided on its upper side at a suitable distance in advance of the plunger with a yoke-bar 33. The same is connected by suitable links 34 to bell-crank levers 35, that are mounted on the sides of the press-box, as at 36. The said bell-crank levers are connected by suitable cords or other flexible connecting elements 37 to the yokes 23 of the condensing-boards 21. The said cords 37 pass over suitable diection-sheaves 38.

From the foregoing description and by reference to the, drawings it will be understood that at each instroke of the plunger the connections between the latter and the condensng boards are slackened, thereby causing the springs 25 to dispose the condensing.- boards in the inclined positions shown in Fig. l, where they serve to arrest and retain a quantity of hay thrown between the vertical sides 19 and prevent the same from passing through the feed-opening 20 while the plunger is compressing the partially-formed bale in the press-box. 0n the ensuing outstroke of the plunger the latter, through the connections hereinbefore described, draws the upper sidesof the condensing-boards 21 inwardly, thereby disposing the said condensing-boards in a vertical position, slightly condensing the hay below the teeth 27 between them, and causing the hay to drop from between the said condensing-boards and the vertical sides 19 through the feed-opening 20 into the baling-chamber 17 in rear of the plunger. Such hay as is fed to the press while the condensing-boards are thus operating is retained above the teeth 27 to be dropped therefrom between the condensing-boards as the latter subsequently open. As each bale is formed a division-block 39 is placed behind the finished bale. The construction of the divisionblock is illustrated in detail in Fig. 5, and the same is provided on its upper and lower sides with grooves 40, in which are disposed friction-shoes 41, that are movable therein and are pressed outward by springs 42 into frictional engagement with the upper and lower sides of the bale-chamber. The said divisionbloGkS are provided on their front and rear sides with grooves 43, through which the binding-wires may be passed around the bale, the said grooves registering with longitudinal slots 44 in the sides of the bale-chamber to permit of the binding of the bales in the usual manner. It will be understood that when a bale has been formed and pressed rearward by the action of the plunger until the divisionblock in front of the bale has passed the dogs 28 the latter by engagement with the divisionblock effectually prevent the finished bale from moving forward while the plunger is coacting with the division-block in the formao o anothe bale- On the front portions of the sills 1 is a frame 44 of suitable construction, in which are journaled a. vertically-disposed power-shaft 45 and a vertically-disposed crank-shaft 46. Each of the said shafts is provided with a pair of sprocket-wheels. The sprocket-wheels 47 on shaft 45 are connected to the sprocket-wheels 48 on the crank-shaft 46 by endless sprocketchains 49. The proportions of the respective sprocket-wheels may be varied to cause the crank-shaft to rotate at any desired rate of speed with relation to the power-shaft 45, and in practice I employ a number of sprocketwheels of varying sizes, which are adapted to be placed on the respective power-shaft and crank-shaft in order to cause the latter to make as many revolutions to a single revolution 'of the former as may be desired. The crank 50 of crankeshaft 46 is connected to the plunger-rod by a pitman 51, and thereby motion is communicated to the plunger, as will be understood. A suitable sweep-lever 52 is attached to the upper end of the vertical power-shaft 45, and one or more horses may be attached to said sweep-lever to furnish power'for the press.

A feed-table'53, which is preferably of the construction shown, has its inner end detach.- ably connected to one of the vertical sides 19 of the press-box, and the outer portion of said feed-table is supported by a brace-.bar 54, the ends of which are inserted in keepers 55, with which said feed-table and the press-box are respectively provided. The said feed-table is supported in an inclined position and hay thrown thereon by gravity is fed therefrom to the press, as will be understood.

The bearings for the power-shaft 45 are adjustable by means of bolts, as shown, whereby the chains 49 may be kept at the required tension.

Having thus described my invention, I claim 1. The combination of a press-box having a feed-opening on its upper side, and vertical side boards extending above and on opposite sides of said opening, condensing boards hinged at their lower sides on said press-box, said condensing-boards being disposed on op posite sides of said feed-opening and between said side boards and having yokes on their outer sides, the ends of which yokes operate in curved slots with which said side boards are provided, spring-arms projecting out- 'wardly from the press-box, connections be tween said condensing boards and said spring-arms, the latter serving to normally open said condensing-boards outwardly from each other, a reciprocating plunger and con-: nections between said plunger and said con densing-boards, substantially as described.

2. The combination of a press-box having a feed-opening on itsupper side, and pivoted condensing-boards above and on opposite sides of said feed-opening, said condensing boards having inwardly-projecting downturned teeth on their inner sides, and means to operate said condensing-boards, substantially as described.
